UNITED STATES PATENT OFFICE.

HENRY A. KAYSAN, OF BROOKLYN, NEW YORK.

OPERATING-TAB LE.

SPECIFICATION forming part of Letters Patent No. 541,360, dated June 18,1895.

Application filed April 26, 1895.

To all whom it may concern:

Be it known that I, HENRY A. KAYSAN, a citizen of the Empire of Germany,residing at Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Operating-Tables, of

the surgeon in performing an operation; and

the invention consists of an operating-table which comprises abase-frame, a tabletop having an exterior frame corresponding to thebase-frame, pivoted crossing-supports connectiug the base-frame with theframe of the table, toothed stays or rack-bars that are pivoted to theframe of the table and adapted to interlock with a transverse cross-rodof one set of supports, and a locking-device for locking the stays inposition after the table has been set into the proper position.

In the accompanying drawing is represented a perspective View of myimproved operatingtable for surgeons use.

Referring to the drawing, A represents an oblong base-frame which ispreferably made of wrought iron, and B the oblong table-top which isalso made of an oblong frame of wrough t-iron b, and a solid glass-plateb supported by said frame, as is customary in surgical operating-tables.The base-frameA is connected with the frame of the table-top B by meansof two pairs of crossing supports 0, O, which are pivoted respectivelyto the inside and outside of the side-pieces of the base-frame A andframe I).

To the frame of the table-top are pivoted near one end at d, thearc-shaped and toothed stays or rack-bars D, which are adapted to engagea transverse rod B of the pivoted supports 0 so as to permit thetable-top to be either in horizontal position, or in forwardly andbackwardly-inclined position according to the position which it isdesired to impart to the body in operating. After the table-top has beenset in the required position, the stays are locked in position on thecross-rod B so as to prevent it from being accidentally re- Serial No.547,250. (to model.)

leased therefrom, during the operation, by means of locking-arms E thatare connected by a rotable cross-rod E and provided with cranks E attheir inner ends, so as to place the armsE in position for lockingagainst the rear edges of the stays D. hen the lockingarms are placed inthis position, the stays are rigidly locked to the cross-rod B andprevented from getting detached therefrom, while the locking-arms imparta rigidity to the the table, which is absolutely necessary forsupporting the weight of the body placed on the table-top.

The locking-arms can be readily unlocked from the stays wheneverre-adjustment of the table-top is required, and placed again in positionso as to lock the stays, as the supports are so arranged that theypermitthe easy and convenient adjustment of the table-top to theposition required for use.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. An operating table for surgeons use, consisting ofa base-frame, a table-top provided with an exterior frame, pairedcrossing supports pivoted to the base-frame and the frame of the top andprovided with a cross-rod connecting one pair thereof, toothed stayspivoted to the frame of the top and adapted to engage the cross-rod, andlocking-arms adapted to bind on said stays so as to lock them inposition on said cross-rod, substantially as set forth.

2.-An operating-table'for surgeons use, consisting of a base-frame,atable-top provided with a frame, crossing-supports arranged in pairsrespectively pivoted to the outside and inside of the base-frame andtop-frame, stays pivoted to the frame of the top and provided with teethon one edge, said teeth engaging the cross-rod of one pair of supports,and locking-arms pivoted to the latte-r pair of supports and adapted toengage the stays, so as to lock them to the cross-rod, substantially aset forth.

In testimony that I claim the foregoing as my invention 1 have signed myname in presence of two subscribing witnesses.

HENRY A. KAYSAN.
